Substitute for application Serial No. 722,659, filed .Tune 27, 1924. This application filed. September 5,

This application is a substitute for our prior application No. 7 22,659, filed June 27, 1924. o

This invention relates to Window regulators and has for its object an improvement in anvindow regulator of the lever type. Regulators of this type are old, and the objective aimed at by the manufacturer 1s I simplicity'in construction so that the producshowing in dotted lines the window regulator installation. v

Fig. 3 is an elevation of the regulator as viewed from the other side showing in dotted lines a second position of the regulator or the position of the same when the window is lowered part way.

Fig. 4c is a vertical sectional VleW taken on theline 44 of Fig. 3.

Fig. 5 is a detail showing the connection of the regulator arm to the lower sash barof the window taken substantially on the line 55 of Fig. 3.

Fig. 6 is a detail perspective of the regulator plate.

' a designates the window regulator plate which is a single stamping and whlch 1s provided with the struck out cup I) which 1s slotted as at a, so that a portion of the segmental toothed quadrant d may pass therethroughand engage the pinion ethe driven member of the clutch mechanism.

The details ofcthe clutch do not form a part of this invention and the details need not be explained. A cup-shaped clutch housing 7 is secured to the regulator plate and houses the clutch parts, and a crank-handle Serial No. 54,608.

clutch and enabling the operator to actuate the driving pinion e, thereby actuating the segmentary quadrant to raise or lower the window.

The toothed regulator quadrant or segment is pivoted to theregulator plate as at h and the lever arm i is riveted or otherwise secured to the quadrant and is provided at its free end with a roller 7' that engages in the sash bar channel is carried by the window. Obviously the rocking of the quadrant by turning the crank handle will cause the window to be raised or lowered.

V Fig. 6 shows the construction ofthe window regulator plate which is provided with the punched-out lip or ear m. which is offset in a plane slightly removed from the plane of the regulator plate. The toothed regulator quadrant when assembled to the regulator plate is adapted to be fitted under this ofi'set ear. Carried by this ofi'set ear is a punched-in depression or boss or point 'n which'is adapted to frictionally engage the exposed side of the regulator quadrant. Also the punched-out depression or boss or point 0 in the main body of the regulator plate is arranged in such a manner as to frictionally engage the underside of the regulator quadrant. This is quite clearly shown in Fig. 4. These frictional bosses or points will frictionally. engage the regulator quadrant and prevent the quadrant from rattling or vibrating between the plate and the ofi'set ear, This provides a regulator construction which eliminates the rattling of the moving parts, as any unnecessary rattling isquite annoying to the automobile owner, yet the amount of frictionis very small due to the small surface.

At the bottom edge of the regulator plate the projection p is bent up as shown clearly in Figs. 2 and 4. The regulator quadrant is secured to the stud g, said stud being rotatably supported in the regulator plate and provided with a slot 1'. A counterbalancing spring 8 has one endengaged in this slot carried by the stud and the other end looped about the stationary qbent up projection or car 1) carried by the regulatorplate. movement of the regulator quadrant which lowers the window winds up this counter-' balancing spring so that the operator when turning the.handle to raise the window is guiding points or bosses is that the same properly guides the stamped metal quadrant wi h respect to the teeth of the pinion.

This is quite important for the reason that adapter bushing.

very often the regulator parts become bent or distorted by the Workman in. making the installation. These points serve as an accurate guide to line up the teeth of the quadrant with the relatively narrow teeth of the pinion so that they will always mesh.

Riveted or otherwise secured to the end of the clutch cup 7 is an interiorly threaded adapter bushing a. This is \arranged to receive which can be turned into it and thereby supports the escutcheon plate 11 The thimble w is rotatably but permanently secured to the hub of the crank handle by spinning over the end of the hub as at the point a. This forms a handle assembly which can be easily coupled up with the regulator by simply fitting the hub over the projecting'shaft Z and turning the thimble down into the What we claim is:

1. In awindow regulator the combination of a regulator plate formed of a stamping, and a regulator segment supported thereby, said regulator-plate having one or more points stamped therein which are adapted to frictionally engage the regulator segment.

2. In a window re lator, the combination of a regulator p ate, and a regulator (segment supported thereby, said plate provided with anear struck out from said plate and offset therefrom whereby the segment may be engaged between the said ear and the mam body portion of pose of guiding the outer regulator segment.

3. In a window regulator, the combination, of a regulator plate, and a regulator se ent supported thereby, saidplate provi ed with a struck'. ont ear ofiset from the plane of the plate to provide a guide for the outer portion. of said segment, said ear provided with a' pressed-in boss for frictionally engagirfg" the said segment.
